Explore PHP variable types, including scalar types (boolean, integer, float, string), composite types (object and array), and resources, with practical distinctions and real-world examples.

Defines PHP local variables, explains their function-scoped lifecycles, and shows how they stay isolated, support memory management, and are destroyed after function execution.

Define a function to demonstrate local variables in PHP, create and print a local variable with echo, and observe its function-scoped visibility.

Understand how PHP function variables, including parameters, internal variables, and return values, reside in function scope and support modular, reusable code.

Learn how variable parameters work in a PHP function by assigning a value inside the function, multiplying by 20, and returning the result (e.g., 10 becomes 200).

Learn how PHP global variables enable data sharing across functions using the global keyword. Explore practical examples like cart totals and config values, and review best practices and risks.

Learn how to declare and access a global variable in PHP using the global keyword, include files, and concatenate values inside functions.

Master PHP static variables to persist values across function calls, initialized once, using the static keyword inside a function to track counters, IDs, and simple caches.

Explore how static variables retain state across function calls, incrementing from zero to one, two, three, as shown in the code. Contrast with regular variables that reset on each call.

Explore PHP's eight active super globals and how they enable cross-scope access. Use $GLOBALS or the global keyword to read and modify variables inside functions.

Learn how to set and retrieve cookies in PHP using name, value, and expires (Unix timestamp), and how $_COOKIE reflects these in the browser.

Learn how the PHP $_FILES super global handles file uploads through a multipart form, moving the uploaded file to an uploads directory, with security not implemented in this lecture.

Explore PHP data types, including string, integer, double, float, boolean, and resources, with echo and quoting rules, plus basic conditionals and a database connection.

This lecture covers numeric, associative, and multidimensional arrays in PHP, compares modern and old syntax, and demonstrates indexing by numbers or strings, foreach loops, and echo printing.

Explore PHP array sorting functions to arrange elements alphabetically in ascending or descending order and sort associative arrays by value in both directions, with practical coding examples.

Master the remaining four php array sort functions as you sort associative arrays by value or by key, in both ascending and descending orders, through hands-on examples.

Explore arithmetic operators in PHP, using a built-in calculator to demonstrate addition, subtraction, multiplication, division, modulus, and exponentiation. See how x and y variables and echo statements reveal operation results.

Explore PHP operators, starting with the assignment operator that sets values like x equals 10, then review comparison operators such as equal, identical, not equal, and greater or less than.

Explore PHP operators in this session, including pre-increment and pre-decrement, and, or, xor, not, modulus, and concatenation. Practice applying these operators in conditional statements to prepare for if statements.

Define constants with define, name them uppercase, cannot start with a number, may begin with an underscore and capital letter, and print to show they are unchangeable.

Learn to implement PHP conditional statements using if, else if, and else; test or, and, and not operators with sample variables e and r to control output via echo.

Learn how the PHP foreach loop iterates over arrays to print each element with echo, using HTML formatting to display various data types.

Learn how a for loop initializes a variable, tests a condition, and increments it to print numbers from 0 to 9 using concatenation and a line break.

Explore the PHP do-while loop by building a simple counter with a do block, echoing values and incrementing x until the condition x <= 10.

Explore how break and continue statements control a PHP while loop, stopping at five or advancing to ten and printing intermediate values.

Learn how to include single or double quotes inside PHP string values by escaping them with backslashes, preventing syntax errors and enabling nested quotes in echo statements.

Master core PHP constructs, the language’s basic units, and how they differ from functions; learn key constructs like echo, print, empty, isset, unset, include, and require.

Explore how PHP handles strings with double versus single quotes, showing how double quotes interpolate variables like $name to output values, while single quotes print literals.

compare print and echo in php by showing that print returns 1 and accepts one parameter, while echo has no return value and supports multiple parameters.

Learn how to use the PHP date function to format dates and times, explore common format parameters, and set time zones for dynamic, readable outputs.
